WAGONAAXLE SPINDLE.

SPECIFICATION forming part of Letters Patent No. 672,606, dated. April23, 19011. Application filed February 1901. Serial No. 46,113. (Nomodel.)

To all whom it may concern.-

Be it known that I, HENRY STooKMAN,a citi- Zen of the United States,residing at Marion,

I in the county of Grant and State of Indiana,

have invented certain new and useful Improvements in Wagon-AxleSpindles; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to wagon-axle spin- I dies, and has for itsobject the production of I an improved appliance of this characterpossessing advantages in point of efficiency and simplicity anddurability of construction.

The nature of my invention will be readily comprehended, reference beinghad to the following detail description, and to the accompanyingdrawings, in which-- vided with a shoulder a, against which abuts abushing C, stepped to conform to the inner side of the box or skein, andsaid bushing is held from rotation by the engagement of a lug c thereonwith a corresponding recess a in the spindle. Near the outer end of thespindle is a shoulder (1 formed by reducing the spindle, and againstthis shoulder abuts a bushing D, which is non-rotatable, a lugd thereonengaging a corresponding recess a? in the spindle. The box or skein hasat its inner end an enlargement b, which rotatably engages the innerbushing; but the outer end of the box or skein rotates in an enlargementd of the outer bushing. The bushings O D support the box or skein out ofcontact with the spindle, so that the latter receives no wear and may beused indefinitely, the bushings being renewed from time to time.

At E is shown a lubricating band of textile material which entirelyencircles the spindle and extends from the inner end thereof to near theouter end. This band fits a reduced part of the spindle and is of athickness to bring it into contact with the inner surface of the box orskein. Oil is supplied to the band through an oil-tube F, which isscrewed at its inner end into a threaded aperture in the box or skeinand extends beyond the hub, where it is provided with a screw-cap f. Inpractice oil is introduced into the tube and passes between all of thebearing-surfaces, any excess being taken up by the band, which thus actsas a reservoir to keep the parts thoroughly lubricated. The band may berenewed from time to time.

By my invention every provision is made for securing a long period ofusefulness of the axleand the box or skein. The bushings may be readilyapplied to existing as well as new spindles and without the necessity oftruing the worn parts, so that skilled labor is unnecessary. Thebushings and lubricating-bands may be inexpensively produced and quicklyapplied and are very eftlcient in operation.

I claim as my invention A Wagon-axle spindle having near each end ashoulder and a recess, bushings encircling the spindle and each abuttingagainst a shoulder and provided with a lug engaging its respectiverecess, a lubricating-band of textile material encircling a reduced partof the axle, and an oil-tube extending through the hub and box or skeinand terminating adjacent to the band.

In testimony whereof I aflix my signature "in presence of two witnesses.
